Objective: The purpose of this study was to investigate the effects of semantic congruence and incongruence on sign identification by using event-related potentials (ERPs).
Background: Sign systems have crucial roles in public spaces and traffic facilities. Poorly designed signs can easily confuse pedestrians and drivers and reduce the efficiency of public activities and urban administration.

Objective: To investigate the time course of positive head-up tilt test (HUTT) for patients with suspected vasovagal syncope.
Methods: Consecutive patients referred to the syncope unit of our center for recurrent unexplained syncope were included. The HUTT consisted of a 30 minute passive basic phase and a 20 minute sublingual nitroglycerin provocation phase if syncope did not develop during the passive phase.
Aims: To investigate the appropriate duration of head-up tilt test (HUTT) needed to induce a positive reaction in patients with suspected vasovagal syncope.
Methods And Results: Consecutive patients referred to the syncope unit of our centre for recurrent unexplained syncope were studied. The HUTT included a 30 min passive basic phase and a 20 min sublingual nitroglycerin provocation phase if syncope did not develop during the passive phase.
